the end customer purchased nanocrystalline epoxy core 13x9.5x5 150k for current transformer, Nanocrystalline core 21x16x10D with plastic case,100k, nano core 25x16x8 with plastic case

DC immune current transformers are important components for energy meters and other electrical instruments. Based on the technology of high permeability and high saturation induction soft magnetic material, we can provide DC immune current transformer cores of good linearity.

5000pcs nanocrystalline core trial order shipped to India, customer use it to produce the common mode choke.

The current transformer DC immune is used to detect AC currents wherever DC offsets exist. The current sense transformers create a voltage when current flows. They are mainly made for detecting AC currents in a circuit. So with a DC bias, the AC measurement can distort.

DC immune current sense transformers are used for sensing the AC currents where DC offsets also exist. The current sense transformers create a voltage when current flows. They are primarily made for sensing AC currents in a circuit so having a DC bias can distort the AC measurement.

Common mode choke, also known as common mode choke coil, is commonly used in switching power supplies of computers to filter common mode electromagnetic interference signals.
